What Is Keeping The NA1SS Amateur Station Off The Air?

Amateur Radio on the International Space Station (ARISS) and its partners
are troubleshooting what is keeping the NA1SS amateur station off the air.

ARISS became aware of the problem after an attempted contact with a school
in Wyoming, between ON4ISS on Earth and astronaut Mike Hopkins, KF5LJG at
NA1SS, had to abort when no downlink signal was heard. ARISS has determined
that the problem is not with the radio equipment on board the ISS Columbus
module.

ARISS-International Chair Frank Bauer, KA3HDO, explained that during a 27
January spacewalk to install exterior cabling on the ISS Columbus module,
the coax feed line installed 11 years ago was replaced with another built
by the European Space Agency (ESA) and Airbus. It included two additional
RF connectors to support the Bartolomeo payload-hosting platform installed
last spring on Columbus.

"On 26 January, prior to the EVA [extravehicular activity], our Columbus
next-generation radio system was shut off and the ISS-internal coaxial
cable to the antenna was disconnected from the ARISS radio as a safety
precaution for the EVA," Bauer said. “During the spacewalk, an exte
rnal
four-connector coax feed line replaced one with two RF connections. This
change was made to allow ESA to connect ARISS and three additional
customers to Bartolomeo, as compared to ARISS and one additional RF
customer," Bauer explained.

With the spacewalk completed, the ISS crew restarted the ISS amateur radio
station on 28 January, but no voice repeater or automatic packet repeater
system (APRS) downlink reports were heard and no downlink signal was heard
during an attempted scheduled school contact either. Bauer said that
because the exterior cable is not an ARISS cable, ARISS is working with ESA
and NASA on a way forward. "NASA has opened a Payload Anomaly Report on
this issue. We have talked to both the NASA and ESA representatives," Bauer
said.

AMSAT OSCAR-109 Update

The RadFxSat-2/Fox-1E CubeSat has been designated as AMSAT-OSCAR 109
(AO-109). AMSAT engineering and operations teams appreciate the satellite
community’s cooperation to date and reiterated their request that u
sers not
attempt to use the transponder until further notice. “The proper
identification will allow further characterization of the satellite
s
condition through additional testing,” AMSAT concluded.

RadFXSat-2/Fox-1E was launched on January 17 on Virgin Orbit’s Laun
cherOne,
which carried 10 other satellites into space. AO-109 carries an inverting
linear transponder, with uplink at 145.860 MHz – 145.890 MHz, and d
ownlink
at 435.760 MHz – 435.790 MHz. Telemetry will downlink on 435.750 MH
z.

Happy New Year on Mars!

The countdown to a new year is in many ways a defining moment for our lives
on Earth. Our age, our seasons, filing our taxes, all depend on the
duration of Earth’s orbit around the Sun. On Mars, there are no yea
rly tax
returns, but as the planet also orbits around our Sun, time on Mars is
similarly measured in years. However, there are some significant
differences between a year on Mars and a year on Earth. February 7, 2021
marked what scientists here on Earth consider the start of Year 36 on Mars.
Let’s look at some similarities and differences between a year on t
he two
planets:

* One year on Mars equals 687 Earth days. It takes almost twice as long as
our Earth to orbit the Sun. This means your age would be a lot less if you
lived on Mars! If you would like to feel younger, just divide your current
age by 1.88 and casually mention to your friends that that’s your r
eal
age...on Mars.

* A Martian day is defined, like on Earth, as the time it takes for the
planet to make one revolution around its axis. This is called a sol. A sol
is only slightly longer than an Earth day: 24 hours and 39 minutes.

* Mars has four seasons: winter, spring, summer and autumn. They are
defined by the planet’s position along its orbit around the Sun. Th
e
Martian New Year begins with the northward equinox (northern spring,
southern autumn). As Mars travels through its yearly trajectory, the
planet’s axial tilt causes the northern hemisphere to receive more
sunlight
during the northern summer, and the southern hemisphere to receive more
sunlight in northern winter – just like on Earth. Unlike Earth
s seasons
however, the seasons on Mars are not of equal lengths. This is because the
orbit of Mars around the Sun is more elliptical than that of Earth. For
example, the northern hemisphere spring (southern hemisphere autumn) lasts
the longest, 194 sols, and the northern hemisphere autumn (southern
hemisphere spring) is the shortest season at 142 sols.

* Mars’ elliptical orbit can have important consequences. During so
uthern
spring and summer, Mars swings by the sun closer and faster. The resulting
increase in luminosity heats up the atmosphere, causing turbulence to lift
up very fine particles from the Martian soil. For this reason, the second
half of a Martian year is often marked by fierce dust storms that can
sometimes become planet-wide.

* Like on Earth, winters are cold and summers are warm on Mars, but the
planet’s overall temperature is a lot cooler, it has a yearly avera
ge
temperature of minus 60 degrees Celsius. The planet experiences different
weather phenomena throughout the seasons. A weather phenomenon that
reappears every year around the southern spring and summer is the Arsia
Mons Elongated Cloud, a cloud of ice crystals that can reach up to 1800
kilometres in length. It repeats for at least 80 sols and then disappears
again during the rest of the year.

* The Martian calendar began fairly recently compared to the one on Earth.
The count started in Earth year 1955. This first Martian year coincided
with a very large dust storm in its second half, aptly named ‘the g
reat
dust storm of 1956.’

If you’re looking for a reason to celebrate, here’s to a Ha
ppy New Mars
Year!

Satellite Operating Awards Available

Awards are a big part of amateur radio in all of its various
manifestations, and the same is true for satellite operations. There are a
number of awards that are available for all your hard work on the
satellites. AMSAT sponsors a number of these awards, and others are
available from other amateur organizations. You may not have even known
about some of them, and may have enough QSL cards to qualify now!

AMSAT's Satellite Communicators’ Club award is given to any operato
r for
having made their first satellite contact. To apply for this, and other
AMSAT awards, you should go to the AMSAT.ORG online store and purchase the
award. After completing your purchase, email the AMSAT Awards Manager,
kk5do AT amsat DOT org that you have made the purchase and supplying the
necessary proof of contacts.

The Oscar Satellite Communications Achievement Award is for working 20
contacts, on any satellite or combination of satellites, in 20 different
states, DXCC countries or Canadian Call Areas. Those that have the RAC
CANDADAWARD or ARRL WAS with satellite endorsements, may submit a copy of
their certificate as proof of working the 13 Canadian Call Areas or 50 U.S.
States. All QSOs must be completed from locations separated by no more than
50 miles or 80 kilometers.

The Oscar Sexagesimal Award is the same as the Oscar Satellite
Communications Achievement Award but is given for 60 contacts. All the
qualifications and costs are the same.

Next there is the Oscar Century Award. This is the same as the other two
awards but is for 100 contacts. Qualifications and costs are the same.
Please note that the previous 3 awards are aggregated. Once you have worked
your 20, that applies towards your 60 so you only need 40 more contacts.
The same is true for the 100, once you get your 60, you only need 40 more
for your 100.

The AMSAT Rover Award is given to those intrepid souls who make our grid
counts possible. It is based on a rather complex point system, which is
detailed at https://www.amsat.org/amsat-rover-award/

Finally, AMSAT offers the Robert W. Barbee Jr., W4AMI Satellite Operator
Achievement Award. It is awarded for the submission of 1,000 satellite
contacts on OSCAR-6 or later satellites. There is an endorsement for each
additional 1,000 and a special certificate at 5,000.

For details on each of the AMSAT awards and how to apply for them, see the
AMSAT website at https://www.amsat.org/awards-2/

In addition, the American Radio Relay League (ARRL) offers many of their
operating awards with satellite endorsements for those who complete the
necessary contacts exclusively using satellites. These include the VHF/UHF
Century Club (VUCC) for working 100 different grid squares, and the Worked
All States (WAS) for confirmed contact stations in each of the 50 states.
Those up for a particular challenge can shoot for the Worked All Continents
(WAC) for contacting stations on each of the 8 continents, and DX Century
Club (DXCC) for contacting 100 different DXCC countries on satellite.

AMICALSAT Award Certificates Deadline Approaching

Diplomas for the AMICALSAT satellite are being sent out. If you have not
yet requested yours, you can do so before 28/02/2021.

The satellite has been active since September 3, 2020. The launch of the
Vega rocket went well. According to the project team, the commissioning of
the satellite is in progress and is proceeding normally. The team has
succeeded in stabilizing the satellite and is beginning to test image
capture and retrieval.

The contributions of radio amateurs have been very important for the
project. This has contributed to the commissioning of the satellite. In the
case of AMICALSAT, it is possible to send telemetry to the dashboard hosted
by the Satnogs network via

* a Satnogs station
* the AMICALSAT Decoder software provided by AMSAT-F at
https://bit.ly/3pdTvcm
* the software edited by DK3WN (TLM Forwarder)

Data from AMICALSAT Decoder is also sent to the AMSAT-F database (
https://amsat.electrolab.fr/). To date, more than 42 radio amateurs from
all over the world have contributed more than 28,000 telemetry frames.

In order to thank the radio amateurs who have sent telemetry via AMICALSAT
Decoder software before December 31, 2020, AMSAT-F will issue a diploma.

Rules for issuing the diploma

The diploma in electronic format will be given to all radio amateurs or
earphones that have received data from the Amicalsat satellite and sent
these data to the AMSAT-F database with the "AMICALSAT Decoder" software.

Depending on the number of data received on the AMSAT-F database (
https://amsat.electrolab.fr/), the nature of the diploma will be different
depending on the number of frames received before December 31, 2020 23:59
UTC :

GOLD Diploma for persons having sent more than 5000 frames to the
AMSAT-F database.
Silver Diploma for those who have sent between 2500 & 4999 frames to
the AMSAT-F database.
Bronze Diploma: for those who have sent between 500 & 2499 frames to
the AMSAT-F database.
Diploma without mention for persons having sent between 1 & 499 frames
to the AMSAT-F database

The request for a diploma is done by sending an email to

NASA Awards Contract to Launch Initial Elements for Lunar Outpost

NASA has selected Space Exploration Technologies (SpaceX) of Hawthorne,
California, to provide launch services for the agency’s Power and
Propulsion Element (PPE) and Habitation and Logistics Outpost (HALO), the
foundational elements of the Gateway. As the first long-term orbiting
outpost around the Moon, the Gateway is critical to supporting sustainable
astronauts missions under the agency’s Artemis program.

After integration on Earth, the PPE and HALO are targeted to launch
together no earlier than May 2024 on a Falcon Heavy rocket from Launch
Complex 39A at NASA’s Kennedy Space Center in Florida. The total co
st to
NASA is approximately $331.8 million, including the launch service and
other mission-related costs.

The PPE is a 60-kilowatt class solar electric propulsion spacecraft that
also will provide power, high-speed communications, attitude control, and
the capability to move the Gateway to different lunar orbits, providing
more access to the Moon’s surface than ever before.

The HALO is the pressurized living quarters where astronauts who visit the
Gateway, often on their way to the Moon, will work. It will provide command
and control and serve as the docking hub for the outpost. HALO will support
science investigations, distribute power, provide communications for
visiting vehicles and lunar surface expeditions, and supplement the life
support systems aboard Orion, NASA’s spacecraft that will deliver A
rtemis
astronauts to the Gateway.

About one-sixth the size of the International Space Station, the Gateway
will function as a way station, located tens of thousands of miles at its
farthest distance from the lunar surface, in a near-rectilinear halo orbit.
It will serve as a rendezvous point for Artemis astronauts traveling to
lunar orbit aboard Orion prior to transit to low-lunar orbit and the
surface of the Moon. From this vantage, NASA and its international and
commercial partners will conduct unprecedented deep space science and
technology investigations.

NASA’s Launch Services Program at Kennedy will manage the SpaceX la
unch
service. The HALO is being designed and built by Northrop Grumman Space
Systems of Dulles, Virginia, and the PPE is being built by Maxar
Technologies of Westminster, Colorado. NASA’s Johnson Space Center
in
Houston manages the Gateway program for the agency. NASA’s Glenn Re
search
Center in Cleveland is responsible for management of the PPE.

ARISS NEWS

Amateurs and others around the world may listen in on contacts between
amateurs operating in schools and allowing students to interact with
astronauts and cosmonauts aboard the International Space Station. The
downlink frequency on which to listen is 145.800 MHz worldwide.

Due to antenna problems reported earlier, upcoming ARISS contacts are
probably going to be via the Kenwood TM-D710E radio located in the Service
Module. You may or may not notice a difference in signal when compared to
the Kenwood TM-710GA that is in the Columbus module.

A contact with Bishop Guertin High School, Nashua, NH, multi-point
telebridge via AB1OC, is scheduled for Friday, Feb. 19 at 17:56:36 UTC. The
ISS callsign is presently scheduled to be NA1SS and the scheduled astronaut
is Shannon Walker, KD5DXB. Maximum elevation will be 33 degrees. Watch for
live stream at: https://youtu.be/0-Dsel4_7gM

Congratulations to NA7V for his first ARISS contact as an ARISS telebridge
station! The contact with Red Hill Lutheran School of Tustin, Calif. was
completed on Wednesday, Feb. 10. Astronaut Mike Hopkins, KF5LJG, operating
with the station callsign of NA1SS, made contact at 18:26 UTC on a pass
with maximum elevation of 65 degrees. Congratulations to the Red Hill
Lutheran students and Mike!

Satellite Shorts From All Over

+ NASA will provide live coverage on NASA Television, the agency’s
website,
and the NASA app of the launch and docking of a Russian cargo spacecraft to
the International Space Station beginning at 11:15 p.m. EST Sunday, Feb.
14. The unpiloted Russian Progress 77 is scheduled to launch on a Soyuz
rocket at 11:45 p.m. (10:45 a.m. Monday, Feb. 15, Baikonur time) from the
Baikonur Cosmodrome in Kazakhstan. (ANS thanks NASA for the above
information)

+ U.A.E’s Hope (Al Amal) orbiter arrived at Mars on Feb. 9, firing
its
thrusters for 27 minutes to successfully enter Martian orbit. The U.A.E. is
the first Arab country, and the fifth overall, to reach the planet.
Meanwhile, China's Tianwen-1 entered Martian orbit on Feb. 10 for a period
of checkout before a planned release of its instrument-laden lander and
rover sometime in May. And next week, on Thursday, Feb. 18, NASA's
Perseverance rover will slam into Mars’ atmosphere at hypersonic ve
locities
and eventually find itself sitting alone on the surface seven minutes later
(hopefully all in one piece). The Mars fleet is arriving! (ANS thanks The
Orbital Index for the above information)

+ After an incredible 43 years and 22 billion kilometers, Voyager 1 and 2
are still delivering science (which takes 21 hours to reach us at the speed
of light). Using data from both craft, scientists have found evidence for
electrons getting reflected off of shockwaves created by our Sun’s
coronal
mass ejections, which then spiral along interstellar magnetic field lines
while accelerating to great speeds (scientific paper at
https://iopscience.iop.org/article/1...8-3881/abc337). (ANS thanks
The Orbital Index for the above information)

+ NASA announced Feb. 9 it wants to obtain a seat on the next Soyuz mission
to the International Space Station, launching in just two months, to ensure
a U.S. presence on the station in the event of any commercial crew delays.
There are no known issues with SpaceX’s Crew Dragon spacecraft, one
of
which is currently docked to the station for the Crew-1 mission.
“Experience has shown that new launch capabilities may encounter
unanticipated delays or difficulties maintaining initial schedules,
NASA
noted. (ANS thanks Space News for the above information)

+ If there's an advanced extraterrestrial civilization inhabiting a nearby
star system, we might be able to detect it using its own atmospheric
pollution, according to new NASA research. The study looked at the presence
of nitrogen dioxide gas (NO2), which on Earth is produced by burning fossil
fuels. In their study, the team used computer modeling to predict whether
NO2 pollution would produce a signal that is practical to detect with
current and planned telescopes. They found that for an Earth-like planet
orbiting a Sun-like star, a civilization producing the same amount of NO2
as ours could be detected up to about 30 light-years away. Since NO2 is
also produced naturally, scientists will have to carefully analyze an
exoplanet to see if there is an excess that could be attributed to a
technological society. (ANS thanks Space Daily for the above information)

+ U.S. astronauts living aboard the ISS orbital outpost, on Feb. 14, will
break the record for most days in space by a crew launched aboard an
American spacecraft, NASA said. "They will surpass the record of 84 days
set by the Skylab 4 crew on Feb. 8, 1974", NASA said. Four flight engineers
- Shannon Walker, KD5DXB, Soichi Noguchi, KD5TVP, Victor Glover, KI5BKC,
Mike Hopkins, KF5LJG - docked the SpaceX Crew Dragon spacecraft to the US
module last November. (ANS thanks Space Daily for the above information)
